    [ https://issues.apache.org/jira/browse/HDFS-14202?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16754177#comment-16754177
] 

Íñigo Goiri commented on HDFS-14202:
------------------------------------

For the numbers, I would try to use something more intuitive and put comments.
For example, you can put {{final int blockSize = 11 * 1024 * 1024; // 11MB}}.
Regarding the javadoc you currently have, those are not params or any javadoc entity.
It should be a regular java comment:
{code}
// bytesCopied: 21936966 byteCopied.
// timeUsed: 12000 milliseconds
// item: set DiskBalancerWorkItem bandwidth as 10
// Expect return sleep delay in milliseconds: sleep value = bytesCopied / (1024*1024*bandwidth
in MB/milli) - timeUsed;
{code}
